Description
Technical field
Underground engineering construction bored concrete pile cage body is the utility model is related to, specially a kind of rigidity heavier-duty glass fiber-reinforced polymer
Bored concrete pile cage body.
Background technology
Glass fiber-reinforced polymer gradually starts to apply in shield launching arrival, is substituted using the glass fiber-reinforced polymer for being easy to cutting
Reinforcing bar at building enclosure hole and realize that shield is directly cut, this is a kind of current trend for carrying out shield launching and receiving,
The security risk due to cutting armored concrete and bringing can be exempted.
Because the modulus of elasticity of glass fiber-reinforced polymer is only 21% or so of reinforcing bar modulus of elasticity, glass fiber-reinforced polymer cage is fabricated to
Rigidity has larger difference compared with regular reinforcement cage after type, and the self stability of skeleton is poor when fiber bar cage lifts by crane, and stress-should
Varied curve shows obvious linear relationship before fracturing, and strong influence glass fiber-reinforced polymer cage is steady in lifting, transport
Qualitative and bending resistance, shear resistant capacity, it is therefore desirable to which rigidity reinforcement is carried out to glass fiber-reinforced polymer cage.
It is mainly that steel bar girder is set inside muscle cage that existing bored concrete pile glass fiber-reinforced polymer cage rigidity, which strengthens technology, at present
Strengthen, glass fiber-reinforced polymer is connected with steel bar girder colligation, both ends steel reinforcement cage cage bar and steel bar truss welding.Above-mentioned existing bored concrete pile
Glass fiber-reinforced polymer cage rigidity strengthens technology, mainly there is following several respects deficiency：
1st, steel bar girder and both ends steel reinforcement cage cage bar are welded, and muscle cage, which enters, cuts steel bar girder, Jun Xuyou in the decentralization process of hole
Special operation workers are taken appointment with certificate to operate and completed；
2nd, steel bar girder is cut in muscle cage decentralization process and is taken out, it is easy to glass fiber-reinforced polymer is damaged, to glass fibre
Muscle stress performance adversely affects；
3rd, steel bar girder needs to cut into segment in order to be taken out from muscle cage cage bar hole, therefore steel bar girder can not week
Turn to utilize, every width muscle cage needs, from new processing installation, it is more to produce waste material；
4th, every width muscle cage steel bar girder cutting quantities is larger, work efficiency is low, and time-consuming, and it is steady to be unfavorable for cast-in-situ bored pile hole wall
Fixed and cost control.
The content of the invention
The utility model operates limitation, nothing to solve to exist when existing glass fiber-reinforced polymer bored concrete pile cage body rigidity is strengthened
Method turnover is utilized, cutting is wasted time and energy and the problem of easy damaged glass fiber-reinforced polymer, there is provided a kind of rigidity heavier-duty glass fibre
Muscle bored concrete pile cage body.
The utility model adopts the following technical scheme that realization：Rigidity heavier-duty glass fiber-reinforced polymer bored concrete pile cage body, bag
Glass fiber-reinforced polymer cage body and the reinforcing bar cage body of lower both sides disposed thereon are included, two footpaths are provided between the upper and lower external side of two steel reinforcement cages
Include some vertically arranged and annular spread reinforcing bar master in 90 ° of distributions and the channel steel shape shaped steel of notch outwardly, reinforcing bar cage body
Muscle, reinforcing bar cage bar inner side are provided with the ring-type stiffeners of some distributions up and down, spiral reinforcement hoop are provided with the outside of reinforcing bar cage bar
Muscle, the both sides up and down of channel steel shape shaped steel are provided with the U-shaped steel muscle that both ends are threaded and are enclosed in reinforcing bar cage bar, U-shaped steel muscle
Both ends be screwed with the locking nut for being close to channel steel shape shaped steel inner face.
The structure design makes up the bullet of glass fiber-reinforced polymer and regular reinforcement by the bending strength of two shaped steel of incorgruous setting
Property modulus difference, realize the integral rigidity of whole muscle cage, meet lifting force request；And the demountable structure of U-shaped steel muscle is real
The requirement that turnover utilizes is showed, while common laborer is i.e. operable by simple training of telling somebody what one's real intentions are, and overcomes existing glass fiber-reinforced polymer
Exist when bored concrete pile cage body rigidity is strengthened operation limitation, utilization can not be had enough to meet the need, cutting is wasted time and energy and easy damaged glass fibre
The problem of muscle.
The utility model is reasonable in design reliable, meets the rigidity requirement of glass fiber-reinforced polymer, solves reinforcing bar and glass
The problem that the overlap joint cage fabrication and installation of glass fiber bar are yielding, docking is difficult, and the whole cage lifting of unit is realized, save merogenesis and hang
Fill the time of aperture docking, muscle cage hangs the shortening of load hole time, reduce poor strata because steel reinforcement cage enters that the hole time is long and hole
The quality risk of mouth collapse hole shrinkage cavity, while construction cost is reduced, dismounting is easily installed, realizes the requirement that turnover utilizes.
